Title: Rule maintenance system for confirmation item in power system device operating sequence
Inventor: HASEGAWA TSUGIO
IPC: G06F9/44
Filed: 1990-03-27
Abstract: PURPOSE:To input a confirmation item procedure rule by an element of a minimum limit by composing the rule of a condition unit including a device operation, a device type, a command facility, etc., as factors, and an executing unit including states before and after an operation. CONSTITUTION:As command words, four words of 'stop', 'use', 'incorporate' 'release to incorporate' are set. A switch operates an incoming line CB, a bus Ls, etc., in combination with 'open' or 'input'. A command facility column distinguishes the line from the line CB. Similarly, since a switch operation 'to open the lime CB' is different in 'confirmation item procedure' in the cases of the 'stop' and 'the release to incorporate', 'a command word' is used as a factor. In order to distinguish a power line from a load line, 'facility operating method' is set. An executing unit has two executing factors to be inserted before and after 'key procedure' according to a searching result. Thus, the device operation familiar with a judging logic having no feeling of physical disorder can be performed.

Title: Base-isolating structure and damping method thereof
Inventor: HOSOYA YASUYOSHI
IPC: E02D27/34
Filed: 1998-03-11
Abstract: PROBLEM TO BE SOLVED: To enhance the base-isolating effect of a base-isolating structure where large-scale artificial subsoil with a plurality of structures such as buildings and facilitates built thereon is supported on a supporting foundation. SOLUTION: Magnets 6, 7 are disposed respectively on the upper surface of a supporting foundation 2 and the bottom face of artificial subsoil 3 in such a way that their respective same poles (N-poles) face each other. Magnets 8, 9 are disposed respectively on the side face of the supporting foundation 2 and the side face of the artificial subsoil 3 in such a manner that their respective same poles (N-poles) face each other. Therefore, repulsive forces are produced between each magnet 6, 8 on the supporting foundation 2 and each magnet 7, 9 on the artificial subsoil 3 and the artificial subsoil 3 is supported on the supporting foundation 2 without contact.  As a result, the vertical and horizontal vibrations of the supporting foundation 2 in an earthquake are not directly transmitted to the artificial subsoil 3 and the vertical and horizontal shaking of the artificial subsoil 3 is greatly reduced.

Filed: 1986-04-04
Abstract: PURPOSE:To read pictures with high acciracy despite the manual shift of an image sensor or an original by detecting the position and the moving speed of the image sensor and performing the picture reading control based the signals showing said detected position as well as the position ans speed given from a speed detector. CONSTITUTION:The wirting control of a line memory 20 is carried out based on the position signal 101 delivered from a position detector K as well as the signal 104 showing the position given from a position/speed detector 17. Then the picture information 105 is read. At the same time, the scanning speed of a long-size image sensor 3 is controlled in accordance with the manual shift speed of the sensor 3 by a drive control circuit 18 to which the speed signal 102 is supplied from the detector 17. Thus it is possible to read the pictures of an original document M with high accuracy even if a photoelectric converting part S, i.e., the sensor 3 is manually moved. Furthermore a motor and its control circuit can be omitted to move the part S or the original document M since the part S is manually moved. Therefore the power supply scale is also reduced.
